False
When you raise the volume of a condenser mic onstage, the ambient stage sounds are also picked up.
True
False
When phase is an issue, you can try:
Minimizing the phase
Eliminating the phase

Condenser
Dynamic
Both
Ribbon mics are:
More durable than dynamic mics

Transmitter
When setting up multiple wireless units, the typical order would be:
1-do a channel scan; 2-set all the wireless devices to a group; 3-do a group scan
1-set all the wireless devices to a group; 2-do a channel scan; 3-do a group scan
1-do a group scan; 2-set all the wireless devices to that group; 3-do a channel scan
